In general the batiks have a tighter weave due to the type of dye process. You will have a very difficult time telling right/wrong side. There is often a 'watercolor', blended,light-dark look to the ones that are only one color (this can be true of printed blender fabrics too, so check the back side). There is also often a very slightly stretchy feel, again due to the way they are made. Wonderful, beautiful fabrics!
